最近我已将气流升级到更新的可用版本 2.2.1，并得到许多用户使用气流的奇怪错误。

刷新 2-3 次后，我可以看到网络服务器 UI 页面，但它在每一个第一个操作中都会中断。

我为此使用了 LocalExecutor。所有配置都与我去年用于生产的配置相同。

此安装有两个不同之处：

  1. 使用 python pip commond 而不是标准设置安装并作为服务运行。
  2. 不同（升级）版本 - 2.2.1
Something bad has happened.

Airflow is used by many users, and it is very likely that others had similar problems and you can easily find
a solution to your problem.

Consider following these steps:

  * gather the relevant information (detailed logs with errors, reproduction steps, details of your deployment)

  * find similar issues using:
     * GitHub Discussions
     * GitHub Issues
     * Stack Overflow
     * the usual search engine you use on a daily basis

  * if you run Airflow on a Managed Service, consider opening an issue using the service support channels

  * if you tried and have difficulty with diagnosing and fixing the problem yourself, consider creating a bug report.
    Make sure however, to include all relevant details and results of your investigation so far.

Python version: 3.7.10
Airflow version: 2.2.1
Node: ip-1-2-3-4-my-ip-here
